Summary

The processes discussed in this chapter are essential to an effective design; by effective, we mean not only a design that provides the required functionality but also one in which the requirements of the service in operation are fully considered. The design takes into account the immediate needs but also ensures the future requirements for changes, increased capacity, and so on, are fully considered. Through availability and IT service continuity management, the design ensures that the service will be available to an agreed level when required and will be protected from unnecessary risks. The business can be assured that the required level of information security has been built in and that IT management will be able to monitor and manage performance, because the metrics needed will have been included. The service coordination process ensures that all these processes work smoothly together to ensure an efficient handoff to the transition phase.
